Choosing paint for a metal roof

Metal roofs often require paint that offers a high degree of elasticity. This is because metal roofs are prone to stretching and contracting. Traditional home paints are simply not appropriate for a metal roof because they are not elastic enough. As metal roof panels stretch and contract based on thermal expansion, traditional household paint will generally become brittle and crack over time. Peeling usually occurs shortly thereafter. Only paints specifically designed for metal roofs should be used. If the paint does not indicate that it is suitable for metal roofing directly on the label, it is best to omit it. In addition to making sure that the paint you choose is made especially for metal roofing, it is also important to ensure that the primer and top coat are also manufactured for use on metal roofs.

A water-based acrylic paint that is elastomeric is usually the best option to use on a metal roof. In addition to preventing cracking and peeling, this kind of paint is additionally fairly easy to clean should a problem arise. It also happens to be more environmentally friendly. Oil-based paints are also available and used frequently on historic projects, but they can be difficult to clean up in the event of an accident.

What else should I keep in mind?

In addition to considering the paint's level of resistance to peeling and cracking, you should also consider how long the paint is expected to last. A quality metal roof paint will typically last up to twelve years, provided it is applied according to the manufacturer's instructions.

If you are uncomfortable painting the roof on your property or have questions about the correct type of paint to use, feel free to contact an experienced roofing contractor. The roof of your home or commercial building comprises a significant percentage of the investment you have in your property. Selecting the correct roof paint can ensure that your roof will not only look good in the future, but will hold for a long time as well.
